Modal — Technical Overview

Modal is a serverless cloud compute platform purpose-built for AI/ML workloads, offering GPU and CPU infrastructure billed per second with no idle costs. Founded in 2022, Modal provides a Python-native SDK and API that lets developers define, deploy, and scale containerized functions directly from code — no Kubernetes, no Dockerfiles, no infrastructure YAML required.

Key technical characteristics:

  • Per-second billing on all compute: e.g. H100 SXM5 at $0.001097/sec, CPU at $0.0000131/core/sec, memory at $0.00000222/GiB/sec
  • Instant autoscaling to thousands of GPUs and millions of sandboxes, driven by a custom container runtime and fast scheduling engine
  • Multi-cloud infrastructure spanning 20+ clouds, with availability on AWS Marketplace and GCP Marketplace
  • Workload support across inference serving, model training, batch jobs, and code sandboxes
  • Observability integrations with Datadog and OpenTelemetry
  • Identity & access via Okta integration
  • Security posture: SOC 2 Type II compliant and HIPAA ready
  • Open source client/SDK with 1,282 GitHub stars
  • API available for programmatic control of deployments and infrastructure

Starter plan includes $30/month in free compute credits, 100 containers, and 10 GPU concurrency slots. Team plan ($250 + compute/month) scales to 5,000 containers and 50 GPU concurrency. Enterprise pricing is custom.
